Due to the long-term development of water and gas injection in Tahe Oilfield, production increase effect decreases year by year. Based on understanding treatment difficulties stage fractured vuggy reservoir this paper combined with theoretical analysis Nano-sheet technology at stage, such as super amphiphilic interface performance, emulsification viscosity reduction ability, ultra-low core adso...

This paper, by conducting comprehensive analysis on water-flooding reservoir, intensively studied and discussed the characteristics of geological development, determined evaluation indexes development effect, carried out research from five steps, first is introduction part, it conducted indepth study discussion background, significance, literature review, methods four aspects. The second outlin...

We develop a case study planning process by using a strategy for balancing reservoir uncertainties (rock properties), optimum field development scenario (rate schedule and start time) and associated risks in the capital expenditures (price inflation and discount factor). The objective of this development is to recover dry gas reserves from five recently discovered fields in the most cost-effici...

Development of hydrocyclonic separation is introduced first. The characteristics of the dynamic hydrocyclone are described. The laboratory study and oilfield tests of dynamic hydrocyclones were carried out. Some photos indicating flow phenomena inside the hydrocyclone were taken and analyzed for understanding the effect of some varieties on hydrocyclonic separation. Relations of flowrate, and o...

Research on the modeling of rock mechanics parameters is of great significance to the exploration of oil and gas. The use of logging data with the Kriging interpolation to study rock mechanics parameters has been proven to be effective in reservoir prediction and other oilfield applications and can provide additional data. However, there will sometimes be a great deviation due to the limited sa...

Abstract In the late stage of super high water cut development in Sazhong Development Zone, oilfield rules have changed, showing a significant increase production gas-oil ratio. To study factors and laws ratio change, laboratory research on oil/gas/water high-pressures physical properties, field test for single layer development, theoretical calculation modified oil-gas were carried out. The re...

BZ26-6 Oilfield is a kind of deep metamorphic rock buried-hill volatile oilfield in Bohai Sea, China. Its early development plan restricted due to the simultaneous production oil and gas large sections reservoirs, unclear understanding formation fluid properties uncertainty gas-oil interface. Through theoretical research on phase recovery experimental analysis crude characteristics original for...

Novel thermophilic, anaerobic, Gram-positive, rod-shaped bacteria, strains SL9 and OCA1, were isolated from oilfields in France and Australia, respectively. Both strains, together with Thermoanaerobacter yonseiensis KB-1(T) (=DSM 13777(T)), Thermoanaerobacter tengcongensis MB4(T) (=DSM 15242(T)) and Carboxydibrachium pacificum JM(T) (=DSM 12653(T)), possessed genomic (DNA-DNA hybridization stud...
